Abstract
The utility model relates to a natural gas supply mechanism for a diesel oil/natural gas double-fuel engine, which is characterized in that a natural gas high pressure bottle, a natural gas quick electric cut-off valve, a natural gas filter, a natural gas pressure reducing valve, and a natural gas common rail valve are connected orderly and in sequence through a natural gas high pressure pipe, and the natural gas common rail pipe is respectively connected and communicated with a natural gas supply arranged on the connecting point of an air inlet pipe of a diesel engine and air inlets of every cylinder. The utility model can realize diesel oil / natural gas double-fuel start without changing any structure of original diesel engines. The utility model has the advantages of simple use and installation, high safety, and application for various natural gas engines.
Description
The utility model relates to a kind of rock gas feed mechanism of diesel/natural gas dual-fuel engine.
Along with the attention of society to environmental protection, and people are also just high more to the requirement of air quality to the improving constantly of environmental consciousness, thereby emission of automobile wastes has been had certain standard.And diesel engine is more serious to the pollution of air.Many in the world at present at the development of natural gas motor, particularly electric empty multi-point injection, diesel oil ignited in a small amount be the most promising natural gas engine, and diesel/natural gas dual-fuel engine is more suitable for being used for the large-scale bus in city.But also there is not directly to provide at present the device of rock gas to diesel engine.
The purpose of this utility model is to provide a kind of structure that does not change former diesel engine, can be as the rock gas feed mechanism of the diesel oil/natural gas duel fuel engine of duel fuel engine.
The purpose of this utility model is achieved in that to be that duel fuel engine is that the basis of diesel engine is provided with the rock gas feed mechanism, this mechanism is linked to each other and communicates by rock gas high-voltage tube order successively by rock gas bomb, rock gas quick electric cut-off valve, rock gas filter cleaner, rock gas reduction valve, rock gas common rail pipe, the rock gas common rail pipe again respectively be arranged on the diesel engine suction tude and be connected with the natural gas supply device of each cylinder air inlet joint and communicate.
The utility model need not change any structure of former diesel engine owing to adopt said structure, just can realize that diesel/natural gas dual-fuel starts.The utility model uses and very handy and safe is installed all, is applicable to the port-sequence-injection diesel/natural gas dual-fuel, and port-sequence-injection pure natural gas adopts electronic control or non-electronically controlled all kinds of natural gas engines.
Provide specific embodiment below in conjunction with accompanying drawing, further specify the utility model and how to realize.
Fig. 1 is the utility model overall structure schematic representation.
Fig. 2 is the structural representation of the utility model natural gas supply device.
As shown in Figure 1, the feed mechanism of diesel/natural gas dual-fuel engine, be that the rock gas feed mechanism is set on diesel engine 8, this mechanism is by rock gas bomb 1, the electronic repid cut-off valve 3 of rock gas, rock gas filter cleaner 4, rock gas reduction valve 5, rock gas common rail pipe 7 links to each other and communicates by rock gas high-voltage tube 6 order successively, rock gas common rail pipe 7 again respectively be arranged on diesel engine suction tude 9 and link to each other with natural gas supply device 10 that each cylinder air inlet joint is provided with and communicate, also be provided with manual repid cut-off valve 2 in the outlet port of rock gas bomb 1.
As shown in Figure 2, natural gas supply device 10 is arranged between the suction tude 9 and inlet cylinder 13 of diesel engine 8.Natural gas supply device 10 is that half part has the valve seat 11 of placing solenoid valve thereon, with have suction port 17 and the air supply channel 12 that communicates with rock gas common rail pipe 7, lower half portion of air feeder 10 also has an end and communicates with engine air suction tude 9, the air passageways 16 that the other end communicates with the intake duct 13 of cylinder, natural gas supply passage 12 communicates with air passageways 16, and being connected at 12 mouthfuls of places of natural gas supply passage can be directly to the rock gas air pipe 15 of cylinder for rock gas, this air pipe extends to the surrounding edge place of the intake valve 14 in the inlet cylinder, form an angle with intake valve 14 plane shape, be beneficial to the even air mixing that rock gas enters.
